Looks awesome but it's unfair comparison given the Jag has 5 ltr V8 and costs around £120,000, compared to the Alfas poky 2.9 ltr V6 and originally cost about 60k.Since then the Jaguar XE SV Project 8 has gone even faster, although it is less of a road car. I believe, though not certain, that the Jag still holds the 4-door saloon record.
