## Why this model

The BAC Mono is an incredibly unique, road-legal single-seater that offers an unparalleled driving experience. It's essentially a race car for the road, known for its phenomenal handling, blistering acceleration, and pure, unadulterated connection to the tarmac. It's a highly exclusive vehicle, hand-built in the UK, making it a true collector's item that tends to hold its value well, often appreciating if well-maintained.

## What you should pay

Pricing for a BAC Mono is highly dependent on its specific build, mileage, and condition. These cars are rare and often sold through specialist dealers or private collectors. Expect prices to be firm, reflecting its exclusivity and performance. Unlike mass-market cars, depreciation is less predictable and can even see appreciation for well-maintained, desirable examples, especially the 2.5L models.

## Which trim to buy

The 2.5L version, produced from 2016-2019, offers a fantastic balance of performance and value. It benefits from the more powerful Mountune engine compared to the earlier 2.3L models, providing a significant boost in performance without the higher premium of the newer Mono R or the latest generation. It's a proven, exhilarating package that represents a strong entry point into BAC Mono ownership and has shown excellent value retention.

## What to check before you buy

- Wear on high-performance consumables (brakes, tyres, clutch) due to track use
- Potential for specific electrical gremlins
- Ensuring proper maintenance history is crucial due to track use

## Running costs

Running a BAC Mono is not for the faint of heart or wallet! Fuel costs will be high due to its performance nature (expect around 20-25 MPG). VED (road tax) will be £190 per year for a 2018 model. Insurance will be extremely expensive, requiring specialist policies, likely £2,000-£5,000+ per year depending on driver profile and usage. Servicing must be done by BAC or a highly reputable specialist, and parts are bespoke, leading to high maintenance costs. Consumables like tyres and brakes will also be costly and wear quickly with spirited driving.

## Key stats

- **Fuel Type**: Petrol
- **Horsepower**: 305-340 bhp
- **Mpg**: 20-25 MPG (combined)
- **Reliability Score**: Not rated by conventional reliability surveys due to bespoke, low-volume production.
- **Safety Rating**: No Euro NCAP rating; designed for track performance with inherent safety features for a single-seater.

## Depreciation forecast

| Year | Estimated value | Retention |
| --- | --- | --- |
| 2026 | £125,000 | 0% |
| 2027 | £126,000 | -0.8% |
| 2028 | £127,000 | -1.6% |
| 2029 | £128,000 | -2.4% |
| 2030 | £129,000 | -3.2% |

The BAC Mono is a highly exclusive, hand-built vehicle, which means its depreciation curve is very different from mass-produced cars. Well-maintained examples, especially those with desirable specifications like the 2.5L, tend to hold their value exceptionally well, and some may even appreciate over time as collector's items. The initial steep depreciation of a new car is largely absorbed by the first owner, making a used purchase a more stable investment, potentially even seeing a modest gain.

Total value lost since new: -3.2%.
