think what the lifespan of the engine is if some small debris makes it into the engine if the turbo freezes up when it is spinning 75,000 rpm
The speedometer cable needs greasing at a minimum. Hopefully there will not be any frayed strands in it.
With regard to shocks, it depends on what you want. If you want good handling, Bilsteins are the choice albeit an expensive one. Lifetime warranty and they never seem to change in ride characteristic . KYB is a much cheaper alternative and is the Japanese attempt to copy the Bilstein but they don't come close to comparing. My experience is that they work okay on the strip as well.
QA1 makes some single adjusting shocks that can be softened up in one direction and I have seen some that worked pretty well for both street and drag.
Monroe and other such cheap shocks wear out very quickly and cheap is their only quality. They are okay on the strip, I guess...but they suck on the street and get worse each month but if you are determined to be as cheap as possible and don't care about good handling or controlled ride, then hey, they are cheap. You get what you pay for.
