Godfrey, Most modern FWD drivetrains can't be removed by pulling them up, there's simply not enough room to get the engine and transaxle out that way (The LH cars are an exception, but you still normally drop the engine/tranny when working on them).
If you haven't worked on most post-1980 cars, which are the vast majority of FWD designs, you probably shouldn't be commenting as an authority on servicing FWD drivetrains. Because you aren't an authority as your experience predates 90% of the designs to hit the market. And comparing servicing costs on two relatively exotic cars is probably not a good method for making assumptions on anything (Yes, the MR2 is fairly rare and exotic despite being a Toyota with a relatively off the shelf driveline). That's the notional equivalent of commenting on the last generation Celica's reliability based on your experiences with a Lotus Elise 190 (Same basic driveline there too) -Adam Godfrey DiGiorgi wrote: > The engine and transmission of all the FWD cars I've worked on was > most easily removed by pulling them up out of the engine compartment. > Some come out most easily as a unit.
