....has some sort of catastrophic failure mode.
Corvette 427 engines have thrown lots of rods.
BMW M5 V10 engines supposedly grenade at 60,000 miles. All of them. The internet said so.
Mazda RX-8 engines explode if you fire them up and only drive them for ten minutes. Kills the apex seals don't ya know?
E39 M5's all have bad cam phasers that need replacing.
1990 Miatas with the "short nose crank" all break their crankshafts.
Lotus Elise engines will oil starve their cams if you track them with sticky Hoosiers.
The list goes on and on.
Just add $3,000 for a professional IMS aftermarket install to the purchase price of any 1997-2004 Boxster and just spend the money on yours to get it R&R'd if you are trying to sell her.
It's just the world we live in. Complaining about it will not change the perception out there on the ground.
It IS what it IS.
Get busy livin', or get busy dyin'.
