Not true - all versions of the Mk3.5 vRS came with 18” Gemini wheels as standard. Both 230ps and 245ps variants also had 340mm front brakes - the difference is that the 245 has 310mm vented rear, rather than 272mm solid. The easiest way to tell a 230 vs a 245 is to take a look at the rear brakes. The interior stitching on the 230 is also white, whereas the 245 is red - this is probably the most useful when looking at an advert. You can also check the door sticker for the engine code. 230ps models will be CHHA or DKTA, whereas 245ps will be DLBA, DHGA or DKTB. The DKTA and DKTB variants are Euro 6 with the GPF. You’ll find people claiming that the 245 has black exhaust tips - this isn’t true. They were, technically, meant to, but a lot of them didn’t. The 230 was phased out around 2018, but build dates and dealer stock means some do exist with later registrations. You want to get the 245. The extra power is irrelevant, along with the rear brakes - but you want it for the LSD and DQ381. Nothing wrong with the 250, but the 7-speed ratios are just that bit more friendly. The LSD, frankly, makes the car what it is. You’ll find that the prices are pretty much the same - whether it’s a 230, 245, 245 Challenge or whatever. The base build spec of both cars was the same - that’s how my 2020 car has ACC, the digi dash and £600 worth of black paint on the spoiler, but manual folding mirrors and no heated seats. If you want to do some research on the 230 versus the 245, you can compare the GTI to the GTI PP. It’s the same thing. There are lots and lots of posts about this - just use the search function.
