Ok, Troy pretty much summed up the 260RS bar a few things... and one VERY important thing.
The series 1 (97/10 - 98/7) and the series 2 (98/8 - 01/9) are pretty much the same except:
- Cruise control is omitted on the series 2
- Series 1 (black, white and silver colors avail.) Series 2 (Black pearl and Silver avail.)
- Series 2 has some kind of variable valve timing (sorry, no more info on this)
- Series 2 has discharge headlights, Series 1 doesn't
- Series 1 has front and rear spoilers, Series 2 doesn't (don't know what they class as 'spoilers' though! extra extensions on the bumpers maybe)
And the big one...
- Series 1 has 'normal' 4WD, Series 2 has ATTESA ETS...
I trust Car Sensor, they (along with Goo) are the authorities on Japanese cars here. The no ATTESA thing with the Series 1 is bound to cause some concern, but I can't see why Car Sensor would make an error that big... like I say, they're usually spot on.
