Fun to drive when it was in my possession
 Repair shops have had "ownership" of this vehicle an estimated 6 months of my 3.5 years of ownership. I put $2800 into turbo purchase, $1500 into labor then a new turbo blew so another $1500 for labor since the subframe had to be dropped again to install the new turbo. For what the car is worth I've had turbos replace, replaced the valve cover myself due to pcv crack, injectors replaced, fuel pump replaced so I've spent almost half of the cars worth in repairs!!!!!!. Maintenance wise just a nightmare, but a fun car to drive.
