Looking to get a '98 BMW 528i, but need advice

[Famine]

the only thing that went wrong with it is the cooling system

Yup. Baron blew his coolant out in one hit a few weeks back. Luckily I'd identified the fault and was already carrying the spares - a whole £2.80 that cost.

And that was only because a garage checked the coolant and forgot to prime the system.
