On average, I think south manchester holds the more afluent areas, perhaps where you’d be looking to move too if she’s failry well off. Perhaps Lymm would be a good location, easy 20 min commute into the center and yet far enough out that your on the green belt of cheshire, Ideal for a quick doorstep ride through the countryside, down the transpennine trail, or the wandering canal through the cheshire planes. You’d be close to the M6, M56, M62 and M60 motorway networks that will get you to a massive selection of riding within 30 minutes. Delemere forest, peaks, lakes, rivington, north wales, macclesfield forest, lee quary, etc etc etc. I live in Davyhulme, and often ride down to lymm through the farmland, nice area, shed loads of nice pubs in and around the area for the pub ride, just got its own bike shop too. wish I could move there myself.
