So these are two cars that are currently on my radar. I haven't driven either, but have driven the IS250 F-Sport last week. Came away very impressed with the interior, especially the seats. I wasn't overly fond of the center stack of the IS, but I don't think it would be a deal breaker. The Q50 I haven't even seen the in the flesh yet, but am heading to Halifax in November and plan on testing driving one then.
I priced up both vehicles as to how I'd buy them and the price is extremely close........IS350 F-Sport is $48,950 and Q50 Sport is $47,950. Both are RWD models. Our local Lexus dealership won't have an IS350 in stock for another 3 months so it looks like I'll have a lengthy wait to test drive either of them.
