Does anyone else have trouble with the Astra SXi (2003) seats? No matter how I put the seat my right leg really aches. It's almost as if the seat does not go back far enough with the right height for using the throttle comfortably. The brake and clutch pedel are fine. I've tried cushions but they dont help a lot. I've never had a problem in any other car. Anyone know of any possible modifications? I've spoken to Vauxhall and they won't touch the seat for insurance/liability issues. I don't want to get rid of the car but if it carries on I'll have to get rid of it.
