I hope you're going to keep the stock engine intact. I've seen teh '85 GT's on the top 10 list to keep stock.
That was me and my daughter Sammie somewhere around our white '89. I met a lady there Sat night that has a white '88 McLaren. She bought it brand new and it has about 200K on it. It's her daily driver and needs some work (I should have gone to look at it).
