I've been enjoying my GLC63s coupe very much but feeling that it lacks a couple of options I really wanted, mostly the performance exhaust and CarPlay, HUD would be nice but can live without. Facelift GLC will serve me well but I'm also fancy a change so I 've been eyeing on a couple of E63s. I usually use WBAC/motorway to compare the value - as I most likely will sell through them (again), and estimate how much it will 'depreciate' once I made the purchase. So for same age and mileage, at same ball park asking price, GLC63s coupe always fetch a few grand more when valued by WBAC and even more so on motorway. With the E class at higher price point when new, what makes the difference? I can only think that small SUVs are popular and in higher demand but the E63s are not exactly had to sell models is it? I kinda liked the experience when I sold my last car to WBAC and I read some positive comments towards motorway, which would be my preferred option but it looks like if I go with an E63s I will probably end up selling private as the quoted price are all very low to this model. Any comments are welcome, just want to see if I'm missing something.
