After 3 of these monster R129 Mercedes showed up this past summer, we got a tip for another one on eBay from Portland, Oregon. It’s a short list of cars that have over 7 liters of displacement, and pretty extreme for Renntech to punch out the normal 6.0 liter V12 in the SL an extra 1.4 liters. A couple things always seem come up with these cars: time/space-bending power in a dated chassis, and massive depreciation. I’ve always fantasized about having a Benz that could light up the rears on the highway, so maybe this is the most financially feasible way to achieve that goal.
The seller’s 2 cents:
This is an extremely rare Mercedes SL600. It was converted to a RENNtech in 1999, and has a 7.4 liter 575 HP engine with camshafts and ported and polished heads. It also carries a RENNtech resonator by pass, RENNtech rear muffler, oil cooler, CF air intake, transmission upgrade, ASR delete switch, larger front and rear sway bar, Alcon 14″ front brakes and AMG 18 inch Aero wheels all verified through RENNtech. The Customer spent $73,681.00 to do this RENNtech conversion. The car is in spectacular shape, with books and all four Keys.
In the same sleeper green as the one Evan found this summer, this one is extra sleepy with standard AMG monoblocks and completely shaved identifying badges. Nice to see another one that’s been driven, having covered 89k miles, but the flipside is that you’ve got a 90k-mile tuner V12. Right. Anyways, while it’s certainly not the best looking R129, that’s kind of the appeal here: scary power in as plain-jane an exterior as Mercedes can do. No bites at $20k yet, we’ll see if even that is too high for a car whose monster in the engine bay is only matched by its monster depreciation.
