Vauxhall has added two new models, the Exclusiv and Exclusiv XP, to its Astra TwinTop range.

Standard specification for the Exclusiv and Exclusiv XP models includes 18-inch alloys, heated leather front seats and keyless entry.

Also included as standard are heated power mirrors, a three-spoke leather steering wheel and sport switch, which quickens throttle and steering response.

In addition to the TwinTop Exclusiv (which replaces the Exclusiv Black edition), the Exclusiv XP model gains a VXR styling pack as standard, with a body-coloured lower front spoiler, rear lower skirt, lip spoiler and side sills.

As with all TwinTops, both of the new model variants feature a three-piece electro-hydraulic roof which can be raised and lowered in less than 30 seconds.

Customers can choose between a 1.8VVT (138bhp) and 2.0-litre Turbo (198bhp) petrol engines, along with the frugal but powerful 1.9CDTi (148bhp) diesel engine.

Prices start at £19,295 for the manual 1.8VVT Exclusive, with the 1.9CDTi costing £21,265. The same engine choices for the Exclusiv XP cost £19,995 and £21,965 respectively. A 1.8VVT engine with automatic transmission is also available on both models at an additional cost of £1,035.
