130i m sport or 330i / ci sport??

[jay123]

i am looking for a few words from the wise...

what would be a good price to pay for an auc 130i m sport, 55reg 12K miles (advertised for £18750)
an auc 330i sport saloon 20k miles 54reg, leather, manual, (advertised for £16500) and how much a similar coupe would cost.

also what would be the likely PX a dealer would offer me for my 316ti sport, late 54reg, 12k miles mint cond.

i am in two minds on whether i should keep my current car of switch.

also opinions on both cars would be good as well.

TIA
