Dear all X3 gurus
I'm in the process of purchasing a X3 here in Thailand. It would be imported from the UK though. The xDrive35d has a quite stiff price over the xDrive30d due to taxes.
My question is about the engine in those two cars. Is it the same 3 liter engine just with a different tuning, or is the engines different as well? If the engines are the same I guess I could tune up the xDrive30d to the same performance as the xDrive35d after I get it?
Thanks in advance for any info!
