Jeez Paul, spent nothing on the outside yet, just a clay bar rub down of the paint. It needs new window tints ($250) and there is a tear in the back seat ($250). I will respray it, I have the tools and have done a few bikes but not sure what that'll cost, maybe $500 in product.
I've spent prolly around $1.5K in parts and about $250 in tools. I had to buy quite a few large spanners and a bush pressing tool. The spanners are way bigger than you need on the bikes.
It was supposed to be a weekender but cripes it drives so well I'm in it daily

But it's a big car inside, similar sized to a statesman. I was looking for a 3 series but couldn't knock this one back.
They say the e39 was the last of the home repair BMW's. I've seen u-tubes of later models and you need a computer to bleed the brakes
