Dollar - Has anybody rented via Dollar at Heathrow?

I have a trip coming come up in December and just did a random search on Kayak and found Dollar to be the cheapers. $125 for 7 days. inclusive of all taxes.

Is that a good rate?

Also- How different is renting a car in the UK, in terms of rules and insurance?

The rate is great...but the sting...
Excess likely to be excessive
Rip-off fuel policy...

YMMV
