Wow lots of replies certainly is an active forum!
I had an inkling that it might be lowered, now you guys have mentioned it as well it kind of confirms it, it's just springs not coilovers but either way I'll probably out it back to stock I'm not personally a fan of lowered cars.
Thanks for the info on the actuator, it does have hids so makes sense, I better get it fixed otherwise I could end up blind oncoming traffic.
Regarding the ramps with jack's, they are really handy and give you that bit more height especially with a low car like the Z4, however they're too steep as standard to drive up onto, you'll need to buy some ramp extenders to go with them but they're fairly cheap.
Lastly the mr2, I had a mk3 and I thought it was brilliant, I did a 2 week 2000 mile trip round Europe in mine and 3 trackdays it never once went wrong, one of the best handling cars I've ever driven, so light on its feet but I'd had it 3 years and decided I wanted a change so got rid. As well as the Z4 I have a ratty mk1 mx5 that I intend to tow to trackdays with my land rover discovery!
