Thinking of upgrading and buying a CLA45. This particular one has a fairly high mileage (70k), and I was wondering if I should be wary before buying. Generally, you have to replace tyres every year, deal with mot and servicing ever year... that’s the usual. But at such high mileage, anything else? potential gear box replacement required? anything? also what would the cost be for such replacements? (approximately) Thanks in advance for your help!
