The car was sitting out in the rain? You'd think after paying to have it restored, the owner would smarten up.

Anyway, it sounds like a 2800CS, given the drum brakes, though I've never seen a 2500CS in the flesh here in the US (never imported by BMW + who else would bother?). The only other major mechanical differences between the 2800 and the 3.0 are the transmission and differential: ZF for the former, Getrag 262 for the latter. There are little differences, such as the 3.0 having intermttent wipers and so on, but the outward differences besides the brakes are practically nil.

Mechanically, it would be nice if the head were the later "updated" head, as the earlier units were prone to premature cracking. It sounds like a carburetted car, and the original Zeniths carbs are a little fussy (tend to leak without proper attention), tho' many folks replace them with similar Weber units, which have problems of their own (more difficult to balance). If properly maintained, the Zentiths are a better unit, IMHO. Otherwise, the big six is pretty bulletproof and easy to keep around. Oh.. the trans: if a 2800 with a ZF, watch out for a beaten 2nd gear synchro -- not the end of the world, but annoying and requires a trans rebuild or swap to fix.
Good luck,
Michael
'70 2800CS
