Well, a new RE650 interceptor is between £6,100 and £6,600 depending on colour and a new Guzzi V7 Sport £9,100 (UK prices). Performance wise there's not a lot between them although the Guzzi has a lot more character and history but is it worth the extra £3k over the RE, hmmm

.
The problem with the RE is now becoming the price of them, back in 2019 they were £4,500 and now they are £1,600 more expensive for the same bike. RE are in danger of pricing themselves out of the market to Chinese brands
The s/h values of RE's isn't particularly great either (although nothing like those of a BSA Gold star, they really do appear to drop and not helped by massive discounts from new either).
I paid £3,400 for my S/H RE in 2023, it is a 2020 model with the chrome tank so in the upper range of price when new. It had 2400 miles on it with a full service history. I doubt if I could have got the equivalent Guzzi for that price or anywhere near it.
The fit and finish is great but the weight isn't even if it's low down, it is 8KG lighter than my 27 year old V4 VFR but with less than half the power! It is great though for what I want it for, relaxed local rides with a bit of scratching and I could still loose my licence on it

.
If I was to get a Guzzi it would have to be a Le-Mans MK1 as a project. A mate of mine has got one in boxes under his workshop bench, it's been there for at least 30 years and every year I ask him to sell it to me and every year he says he's going to get around to restoring it
