You'd be lucky to find it.
It's probably going to be rung.
They'll take off anything that'll identify it, swap the chassis number plate, license plates and sell it on.
Same thing happened to my brother's Triumph Daytona when he was living in Saxmundham in the 90's.
Luckily he had a tracker on his bike... He was pretty confused to get it back with different plates.
He actually said "You've bought back the wrong bike."
Ringing is becoming more and more common now, and it tends to be done in large amounts of cars.
The only thing he can really do would be to note the number plates of any similar cars he sees and run an HPI check on any he sees.
Usually the plates will be off of a stolen car, so you can inform the Police of it's presence on the road and it's number plate.
Try looking on eBay for them and running a few HPI checks.
Most HPI websites cost - but if you dig you might find a free one.
Even if you find a possible match, it's unlikely you'll actually get the car back.
It could be worse though, the same brother had his house burgled in Ashford, he had all of his stuff bundled into his wife's car (the keys for which were on the hook) and they drove off with the lot!
