Old lady drove it...

So I recently acquired a 1980 320i with less than 100k original miles on it, minus a couple dent's near flawless... Only thing I had to do was get a bat, wires, and a clutch and it drives like it was new. I've driven vw's in the past and this is strikingly similar. I think I'm gonna keep it. Any knowledge you wish to impart upon me, any suggestions for inexpensive mods, or maiming is appreciated, except the maiming.
