I do!! It's funny isn't it... the GS monsters the IS in many ways, yet it doesn't quite "connect" with me in the way the IS did - something I took for granted in the IS I guess.
Anyway, the repair and maintenance bill for both the 745i and IS200 were on the rise. The GS, as you alluded, fitted rather nicely in between those two cars, and so I part-ex'd them both.
Still doesn't quite compare to moving from an IS200 to a GMC Seirra though! :P
483k miles is mad! Did it have an engine/transmission rebuild at all?
The GMC has its original engine 5.3 Vortec V8 and is on its 2nd tranny. The engine hardly revs tho it hardly even goes over 2000rpm it has so much torque. I was ctuising at 70mph at 1500rpm lol. It runs good still! Its smooth, quiete and idles perfectly. The brakes are bad dangerously bad tho!I know what you mean about the IS. Theres just something about those cars other than there reliability and build qualityetc
Suprised you complain about maintenance on the iS tho? I found it cheap abd many after markets available unlike the 7er probably
