For reference, here is the work load required for pulling a diff: Pull the under body bracing, the driveshaft, the PPF, both rear calipers, lower control arm bolts at the hubs, axles, and then the diff.
It's largely going to be at best difficult without a lift, not to mention doing it to 2 cars at the same time.
I had an unexpected call this morning. I test drove an S2000, AP2 at a dealership last night, a large Acura dealer not a rinky dink lot, and had one of the worst dealership experiences I have ever had. Granted, part of it was the set up where I got an email and a phone call indicating that I could test drive a 2009 RX-8 and an S2000 without a problem and the dealer advertises that they specialize in sports cars and sports sedans. However, when I got there, I practically had to argue the salesman into a test drive of the S2000, and he danced around doing everything he could to refuse me a test drive in the series 2 RX-8, and basically pushed me out the door.
The general manager called me this morning genuinely hurt by what happened. I was expecting a call from a businessman that pushes volume, not what I got, which was a call from a fellow enthusiast that knows far too much about the enthusiast community to be faking it. So he is getting me back in, said I will skip the salesman and deal directly with him, and he will just hand me whatever keys I want to test drive what I want. Furthermore, we went down my list of cars and he is getting an R3 RX-8 in on Tuesday, just got in 2 BRZs, might be able to get in a C5 by Tuesday, and suggested adding a 370Z, 370Z Nismo, and 135i, to the list, all of which he has and will give me the keys to test.
He is also interested in my MSM, though he agreed that he probably can't give me as much as I want for it (he said $11k is probably doable). But, with the 7% tax on the difference for a trade in, it just might be viable, as it's only a $2k cut in my down payment amount.
We will see. I think I may pull the Hydra, injectors, and try to pull the radiator later tonight, in case I go down there Saturday and he wants to test mine for an offer he will be able to test what I'd be selling.
