Holy hairy schmitt balls thats some good requirements then!

just as a note if available....

The MR20DE gets the same torque at lower rpm and same power as qr20de
140hp and 148lbs of torque are strong figures will rocket any light datto
Smaller engine than qr20 due to smaller bores and rwd config in serena
and other 4wd cars as far as it shows.

Otherwise post 2008 qr25de is a beast and flies even in big cars.

I was looking at these options for stereos, bloody cheap!

Word of warning beware of bluetooth just like wifi cooks gonads,
ovaries & disrupts melatonin levels..tobacco is safer!

Modern but retro interior would be sweet or whats the overall genre you going for?
