I looked at 06 350z roadster with 125k miles with following issues: top does not open and hood + front bumper needs to be repainted. Can anyone recommend the cost of repairing the issues and any hidden issues I should look out for? Thanks in advance.

 

The paint will cost you $2-300 if it's just a respray. As for the top that won't open it could be an inexpensive $30 switch or a $600 controller circuit board. Trouble shooting at home isn't easy and the dealer will want $$$$. Unless you can plan a $1000 to get the top to drop, Run.
