Customer reviews

"You want honest people and good work?"

"Picked my Silverado up from Conrad's a week ago and it's running better than ever. The owner, Jeryme, told me I could probably get some more miles out of it if I needed to wait, and assured me the price for a rebuild would be the same since he does a complete overhaul every time and doesn't patch it. Price quoted was the price I paid."
