e39 wheels

[Scamp's Walker]

Currently have 17inch BBS split rims which are in need of an expensive refurb and rebuild and was debating what to do whilst the wheels are away. Decided to buy a temporary set so I can still use the car and also to use during the winter once the others are back. Have since come across several sets of "Style 5" cross spoke 16inch wheels in immaculate condition and am debating whether to even bother having the refurb done at all and just buying the 16inch alloys instead! Will I notice much difference in ride quality etc. They look similar but are obviously smaller, so tyre prices will be more standard, and for those of you that have them...... are they as much a pain to keep clean as my current ones!
