Revenue rose 44% from $113.9 million a year ago to $163.8 million, and after-tax profit rose 18% from $8.5 million to $10 million.
The half-year dividend was unchanged at 6c per share; Turners' shares were down 1.6% at $3.11 following yesterday's announcement.
Turners chief executive Todd Hunter said the result was another positive half year of growth and while some softening in the used vehicle market was seen during the election period, overall market trends were positive and growth prospects remained strong.
''We're continuing to benefit from our vertically integrated business model. Finance receivables are growing strongly, as are insurance premiums, both on the back of increasing used vehicle sales,'' Mr Hunter said.
All divisions had delivered improvements in revenue and operating profit, with Buy Right Cars and the Autosure insurance business both contributing a full six months of earnings, following their acquisition last financial year.
The automotive retail division's revenue was up 32% to $113.5 million, while operating profit was up 27% to $8.8 million.
Finance division revenue was up 39% to 17.8 million and operating profit rose 12% to $5.5 million.
Turners finance book had continued to expand and total finance receivables had grown strongly to $269 million, up 30% since March.
The insurance division revenue jumped 345% to $22.4 million for the half year with operating profit of $2.6 million. Acquisition Autosure's in-force policies were transferred to Turners in March, with its products representing about 70% of Turners' insurance business.
Turners was on track to deliver a before-tax profit of between $29 million and $31 million for the full year to March 2018, an 18% to 26% increase on the same period last year.
Mr Hunter said the business was in a strong financial position after the recent $30 million of capital raised.
''The outlook for the automotive sector remains positive providing growing opportunities for finance, insurance and vehicle servicing for the Turners Automotive Group of companies,'' Mr Hunter said.
Turners' focus for the second half of the year remained on expanding its retail presence in both cars and trucks and machinery, developing a bundled approach to finance and insurance and building on existing auto servicing and maintenance.
Shareholder equity increased to $200.8 million for the period, boosted by a $25 million capital placement completed in September, plus a further $5 million placement.
