75k for a gallardo spider?

[niccy b]

Hi guys, by jan I'm going to have 75k and want to get a gallardo. I've seen a few spiders for 85, any opinions on if I could get another 10k and get a spider would it be a better decision from a depreciation point of view? I am planning on keeping only 6-8months, what do people realistically expect to loose in that time? Also what are my major costs going to be based on 500miles a month? Many thanks for your advice.........
