Tim,
Replying to a few points: Lesjofor lowering springs are good. (They are Volvo's OE spring supplier)
Similar fuel consumption between 2.0 and 2.3. My 245 turbo started as a 2.0 GL, and the B200E was livelier than I expected and pretty good to be honest. But a 2.3 is a bit nicer to drive, if you can get one.
If you're intending to modify the car, a GL can be a good starting point because they're less desirable and hence bargains can be found. DLs sometimes even cheaper, but beware, they are only 4-speed.
Another option is an SE, have you looked at those?
But, if you want to avoid the hassles of insuring a modified car, I'd hold out for a GLT, which is a nice, quite sporty drive in standard form.
John
