The 04 2.0L models should have the fuel line issue resolved but Kevin/Whitney could comment I'm sure.
I'd check the subframe for rust and the LCA bushings. Check the bottom and rear of the head to block interface for signs of a weeping headgasket but it generally only the 2.5L engines that suffer the most with HG issues. You might also have him pull the intake host on the turbo and check that there isn't any play in the turbo rotating assembly. Maintenance records to 1/10th of the degree of Mike's would be desirable as well

. Also, be cautious about the 1->2 shift quality as those synchros are known to be flaky on the early 5MTs.
