## Verdict

- **Best value year**: 2020
- **Ideal trim**: Alpina B3 Saloon
- **Target mileage**: 30,000–50,000 miles
- **Max previous owners**: 2
- **Target price**: £44,500

## Why this model

The Alpina B3 is a fantastic choice if you want something truly special and understated. It takes the excellent BMW 3 Series platform and elevates it with Alpina's unique blend of performance, luxury, and comfort. It's faster and more exclusive than a BMW M340i, but more comfortable and less 'shouty' than a full-fat M3. It's a proper driver's car that can also be a comfortable daily cruiser.

## What you should pay

For a 2020 model, you're looking at a sweet spot where the initial steep depreciation has passed, but the car is still relatively modern and has plenty of life left. Prices for these are holding up well due to their exclusivity, typically ranging from £42,000 to £48,000 for a well-maintained example with moderate mileage. Be prepared to pay a slight premium for the Touring (estate) version.

## Which trim to buy

The standard Alpina B3 Saloon offers the best balance of performance, practicality, and value. While the Touring (estate) is fantastic for those needing more space, the Saloon often comes in slightly cheaper on the used market. Alpina doesn't really do 'trims' in the traditional sense; the B3 itself is the model, with most variations being optional extras or body styles. Sticking with the Saloon gets you the full Alpina experience without the Touring's slight price premium.

## What to check before you buy

- iDrive software glitches (minor)
- Higher tyre wear due to performance
- Potential for expensive Alpina-specific parts if damaged
- Brake wear can be significant with spirited driving

## Running costs

Running an Alpina B3 isn't cheap, but it's manageable for a performance car. Fuel costs will be around 24p per mile based on 28 mpg and current petrol prices of ~£1.50/litre. Road tax (VED) for a 2020 model will be £190 per year from April 2026, as the premium car supplement will have expired. Insurance will be significant, likely £800-£1500+ annually depending on your personal circumstances. Servicing at a BMW specialist will be around £400-£800 per year, and performance tyres can be costly to replace.

## Key stats

- **Fuel Type**: Petrol
- **Horsepower**: 462 hp
- **Mpg**: 28-30 mpg (combined)
- **Reliability Score**: Good, based on BMW 3 Series platform, but performance models require diligent maintenance.
- **Safety Rating**: 5 stars (based on BMW 3 Series Euro NCAP 2019)

Buying a 2020 Alpina B3 in 2026 means you're getting a car that has already taken the biggest hit in depreciation. Alpina models tend to hold their value better than standard BMWs due to their rarity and desirability, but like any performance car, they will continue to depreciate. This curve shows a relatively stable, albeit still significant, loss over the next few years, making it a good time to buy if you plan to keep it for a while.

Total value lost since new: 37%.

## Alternatives to consider

- Audi S4/RS4
- Mercedes-AMG C43/C63
- BMW M340i/M3
