Some details on both cars would be nice. But hey get what you love. If you want an 86 go for it. Your 98 is cool, but you know it's whatever. It doesn't have to be the fastest thing on the block. But as long as it makes you happy that's all that matters.
Similar to my case. When I bought my Roush I was well into coyote territory in terms of price. Yea, the coyote might be a better engine, but it wasn't for me. I picked what I wanted and to be honest I'd pick it again and again. Then again I haven't found a 10+ mustang I like better than mine.
Pictures would be nice too.
