Featured Car - Michael Samman's 1987 Grand National

A clean stocker...

Michael I purchased this fully loaded 39,000 87 GN from Kirban. It was a nice strong running stock car. Michael was hooked as soon as he felt the boost kick in!

He worked out a plan with Paul from Ron’s Custom Auto to beef up the car yet maintain true street manners. Street manners were important, since the car is driven 7 days a week all year round regardless of weather. The car now has 87,000 miles. Michael recently upgraded his combination to the one documented below.
