Please let us know what they fit.
The Wolf one looks good, and Neil endorses it, which is encouraging, but I'm interested to know if there are alternatives.
I agree the sump plug is very vulnerable, but clearance is better than the cross member on the 3.7 Roadster, and I've yet to touch anything with it (touch wood). The tow eye under the nearside front makes contact first so gives me a warning!
Will do, although what I do know its costing £400 including fitting but excluding VAT!
