If you mean the horizontal rubber strip between the window and the door, they are available from PNM engineering for about £70 a pair (or they can be modified yourself from a 'standard' profile bit - there are instructions availlable.
If you mean the spongy 'A' pillar seals, then see below answer.
mine's from them were 70 plus VAT, nearly 100 quid. after finishing the job i decided if i ever had to do it again i would "refurbish" the seals that i took out.
Complete sets of OE roof seals are sometimes available as a set, or some can be bought seperately, however, Jamie-N in Scotland has adapted EPDM rubber seals to replace ALL roof 'A' pillar and door seals - instructions are on the forum, or he will sell you a complete set (or whatever you need).
I must have missed the bit in the post where jamie said he would sell sets, i gotta contact him
for 4k i would expect to find a car in pretty good condition, the description you give I would stay away from it. but that's just my opinion.
