What Our Customers Are Saying Wimer Sr.-100x100..jpg

Thank God for Russell's in-depth knowledge of these ol critters and Vintage Jeep! I have a, well, lets just say rather demanding customer that is truly critical of the work done on his military equipment and without these great folks at Vintage Jeep I would be up that famous creek!

I was only introduced to Vintage Jeep Parts early this year . I have had many jeeps since I got my first one in 1966 . This is the best parts house I have ever had the pleasure to do business with . Russell has put up with my mistakes and dialed me in many times already! I have many old jeeps I am working on for myself and others and look forward to working with Vintage Jeep Parts for everything they have or can get for me . This is who all businesses should model theirselves after . They are a true bright light in the industry! Sincerely Thank you

Words can not express my thanks to Russell, Our relationship started in 2006 unbeknown to me or Russell as the story tells. When my dad was a live, After my dads passing in 2011 I was asked by my dad to finish his jeep he started in 06. Well it took me about 3 years to go retrieve the jeep which I though was further along that what I found, LOL when I went to pick it up I found bucket of bolts ,frame pieces, Motor parts and transmission disassemble on the bench and body parts every where. I gather them up and ask myself where am I going to get support for this. I had never built a jeep from gr
