Amazing been going to him for 40 years buy from him he is so helpful and nice .Best Bmw parts around !!!! Jim is amazing

I had a damaged oil filter canister on my 72 Bavaria 3.0, and needed to get it back on the road in a week in order to participate in a grueling 1200 mile rally through Northern California. Jim suggested a replacement from a 78 530i... slightly different design, but workable. I received the parts, they fit perfectly. Did the rally, the Cal Melee.. three days and we did every extra optional route, all the dirt options as well... and the car performed perfectly. Drove it hard and not a drop of leaked oil. THANK YOU to Jim and David Stansfield! Great knowledge, perfect solution and very reasonable price! Excellent!

Very knowledgeable and very helpful with everything I need for my car. Highly recommend this place.

Used to be my go to place for auto parts when I had my 1976 Mercedes. Guys working here were so passionate and knowledgeable about cars and their parts and saved me tons of money. Quick to get parts and help out their customers. Fantastic staff and service. A must go place if you car parts.

Ive been coming here for over 15 years. Jim and his brother, Spence have been a very important and reliable resource to any older BMW owners. They are the best!

Jim at Mesa Performance has been an unbelievable help. Whenever I need parts for my 1980 528I (which is often) he always either has the parts in stock or can get them very quickly, at prices that are fantastic. I dont even go online for my parts anymore. He is also very knowledgeable about anything I have asked him, and gives great input on whatever the repair may be. If you have an older BMW this place is a life saver.

I get most of my parts here for my BMW to help support a local business. I did see a negative review of the owner, and while he is polite, he is not exactly a bubbly personality, that being said I think his son helped me in the past and was very friendly and helpful. Overall would recommend buying from here before going online he can get most parts pretty quickly at a reasonable price.

Jim- Knowledgeable, unmatched-outstanding customer service, and competitive prices, and if he doesnt have it he can get it. He also warned me about the E60/ N54 engine. I shouldve listened to him...

The owner went out if his way to get me some rare inventory I was looking for. The owner was polite and knowledgeable. Will return back for additional products. Thanks

I always love coming here, Jim has good knowledge about older bmw platforms and can often have on hand or can get me hard to find older parts for my E30.Its nice seeing a small business that can succeed. I would rather spend my money here than anywhere else.Plus the cats are excellent.

I have ben a customer of Mesa Performance for over 25 years, and I appreciate no end their helpfulness and knowledge. Jim will jump through hoops to help a customer and will spend whatever time it takes to solve a thorny problem. I hope they stay in business as long as I have a 2002 and recommend them without reservation.

Ive been here dozens of times - very knowledgeable, competitively priced, and if they dont have what you need in the store, they can get most any part that same day if you call in the morning. Its the only place I shop our cars - performance, and family.

Great place to get parts for europen cars. Knowledgeable staff. Had an E30 for a few years and got my parts and advice here. Now I have a couple of MBs and am doing the same. Much better than your typical chain parts store where they know next to nothing about cars. The prices are great too. If he doesnt have a part, he usually gets it in a couple of hours. Also has an agressively friendly cat.

Jim is a real treat. Honest prices on a wealth of information thank you so much for your time today looking forward to doing business with you in the future.

I have always bought my stuff from this place. One day we had a miss understanding on what parts I wanted ordered and he refused to sell me what I did need even though he had it on hand. I showed up to pick up my parts and was rude. I called him and he just hung up on me cursing at me. So much for trying to help local business stay in business. No need to be rude Jim to long time customer. Everything is always cheaper online. People forget we dont have to buy at your store. Jim you have no class.

Very knowledgable owner and staff. Honest an fair.They have the kid of knowledge about BMW an Mercedes that cannot be bought or searched on the web.

Jim has been my local go-to source for parts to keep my BMWs & Porches going for a long time. I dont jerk him around and am always respectful of his time.

Great advice which saved money, time and effort! Best prices in So. Cal.

I have been using mesa performance for bmw parts since i bought my first 320i back in the mid eighties, and i used to drive down from brea to buy parts etc from them. If you have questions about how to do anything they have already done it many times. You really cant get that on the internet, at least not easily. Recommend them very highly

One knowledgeable and helpful store for BMW owners.

Great service

Jim always goes out of his way to get what you need!

Great selection of parts
