That sounds like a good deal to me, providing it in good condition. Chances are you will probably want to do a few mods to it, so take this into account when you check it over.
The sportllines are a great model. And with a few minor changes, can really stand out from the crowd. The Recaros wear well, so should not have the usual bolster damage, especially at only 70,000 miles. Have a thorough look over the hood, as these arent cheap to replace.
I've had mine for a few years, and it belonged to my brother-in-law before me, so I've known it for the past 10 years, and am not aware of any major problems.
what colour is it? black or red? I think the red is the nicer as it looks amazing when its clean and polished
