## Why this model

⚠️ Limited UK data — The Cadillac CT4 was never officially sold in the UK, so any models you find will be grey imports. This means fewer MOT tests and less resale history than established brands. However, if you're looking for something truly unique and enjoy American luxury, the CT4 offers a distinctive alternative to the usual German compact executive sedans. It's known for its sharp handling, comfortable ride, and powerful engines, especially the 2.0L turbo which provides a good balance of performance and (relative) efficiency. Be prepared for potential challenges with parts and specialist servicing, as the UK dealer network for Cadillac is minimal.

## What you should pay

Pricing for a Cadillac CT4 in the UK is highly variable and speculative due to its rarity as a grey import. There's no established market value, so prices will depend heavily on the individual seller, the car's condition, and how long it's been in the UK. Expect a wider price range than typical cars, with a ±20% uncertainty band on any estimates. You'll likely be negotiating based on the car's unique appeal rather than a fixed market rate.

## Which trim to buy

The 'Premium Luxury' trim offers a great balance of features and comfort without going for the more performance-focused 'Sport' or 'V' models, which might be even harder to maintain in the UK. You'll get a good level of standard equipment, including advanced infotainment, comfortable seating, and a refined driving experience, making it a solid choice for a unique daily driver. It's also more likely to be found than the higher-performance variants.

## What to check before you buy

- Infotainment system glitches (minor)
- Some owners report interior trim rattles
- Limited parts availability and specialist servicing in the UK

## Running costs

Running a Cadillac CT4 in the UK will likely be more expensive than its European rivals. Fuel costs for the 2.0L turbo engine will be significant, likely around 20-25 pence per mile at current petrol prices. Road tax (VED) for a 2020 model will be £190 per year. Insurance could be higher due to the rarity of the car and the potential difficulty in sourcing parts for repairs. Servicing will require specialist knowledge, which could also lead to higher labour costs.

## Key stats

- **Fuel Type**: Petrol
- **Horsepower**: 237 hp (2.0L Turbo)
- **Mpg**: Approx. 23-26 MPG combined (US figures)
- **Reliability Score**: Average (based on US market data, UK data is non-existent)
- **Safety Rating**: Good (based on US IIHS/NHTSA ratings, no Euro NCAP)

## Trim comparison

| Trim | Price new | Price used | Key features |
| --- | --- | --- | --- |
| Luxury | £33,000 | £18,500 | 8-inch touchscreen infotainment; Apple CarPlay/Android Auto; Dual-zone climate control |
| Premium Luxury | £38,000 | £21,500 | Leather upholstery; Heated front seats; Wireless phone charging |
| Sport | £40,000 | £23,500 | Sport suspension; Performance brakes; Sport seats |

## Depreciation forecast

| Year | Estimated value | Retention |
| --- | --- | --- |
| 2026 | £21,500 | 100% |
| 2027 | £18,920 | 88% |
| 2028 | £16,125 | 75% |
| 2029 | £12,900 | 60% |
| 2030 | £9,675 | 45% |

Given the Cadillac CT4's status as a rare grey import in the UK, its depreciation curve is highly unpredictable and likely to be steeper than mainstream premium sedans. The 'sweet spot' for buying is essentially whenever you find one in good condition at a price you're comfortable with, as its value is driven more by scarcity and enthusiast demand than a typical market. Expect significant value loss over time due to the niche market and challenges with resale.

Total value lost since new: 55%.
