Is the BMW M3 reliable?

Generally yes — the S58 engine in the current car has been strong. But ‘reliable’ here is graded on a BMW M curve. Maintenance is on time, on schedule, expensive when it’s not under warranty.

M3 Competition vs base M3?

Comp adds power, suspension, brakes, and a worse manual option (it’s automatic-only). Comp xDrive adds traction in any weather and the most usable powertrain. Pick by climate and how much you want to row your own gears.

Should I lease or buy an M3?

Leases work well for BMWs because depreciation is predictable and steep. Buy if you actually plan to keep it past warranty and budget for the bills that follow.

Costs people forget

The line items that don’t show up on the dealer’s quote sheet for a BMW M3.

BMW Ultimate Care ends eventually
Once you’re out of included service, the bills get real fast. Brake fluid flushes, carbon cleaning, plugs, transmission services — all north of dealer-equivalent for any mainstream brand.
Run-flat tires are a tax
OEM run-flats are expensive, ride poorly, and don’t last long. Many owners switch to conventional performance tires and a small repair kit — but that’s another decision to make.
Extended warranty is not optional
Out-of-warranty M-car repairs can be $5–$15k events. Most well-informed buyers either keep it under factory or buy a real BMW-backed extended warranty before it lapses.

Reality check before you buy

BMW M3

Will you use it? The M3 punishes you for treating it like an Accord. Insurance and fuel cost the same whether you drive it like an M car or not.
Manual is still available. Insurance is still expensive either way. Pick the one you’ll enjoy.
xDrive vs RWD vs Comp xDrive — they’re basically different cars by the end of the option sheet. Drive all three.
BMW depreciation is patient and ruthless. ‘New’ M3 in 4 years can cost 50% of MSRP. Lease vs buy math matters.
