Help me deside

[KostasCLK]

First of all I would like to say hello to this great forum, this is my first post and I hope not the last one.
OK here is my situation. I am in the market for a new used car after I sold my merc clk conv. I had found this black with light grey interior slk 200K at a used car's lot that had every mercedes code installed and it had the full brabus kit with quad mufflers and monoblock VI 2 pc wheels. Estimated car's price as new 78000 eur new model slk year 2005.
Couple of days ago on the road from work I spotted this 2002 base silver boxster that had a "FOR SALE" sign parked in front of a nice big house. I left my car to go to take a look. I talked with the owner who and found that he was the initial owner of this garage queen with only 24000 km, detailed service records, litronics, tiptronic immaculate condition inside and out. Owner has a cayenne and a 996 turbo and he does not drive the boxster much but as he told me he loves the car as its his first porsche and has to let go due to lack of his garage space. Slk does not look that well taken care of. The hood is full of stone chips and it is not very clean inside too.
Slk is 43000 eur and box is 39000 eur. Slk has 37000 km.
So now I am desperate. I can't deside.
I need the car only for a drive on weekends. I dont drive fast I like cruising in style. Fact is there are lots of slks around here but boxsters are very rare. Should I go for the newer more luxurius car with dvd, navi power seats, hard top or the box that's so babied but a 5 year car already. Forgot to mention I barely fit in the boxster.
Sorry for the long post and I hope I make the right decision. Please be as unbiased as possible.
